OBSERVATIONS ON SCALE-INSECTS (COCCIDAE) V. 133 



Aspidiotus (Selanaspidus) articulatus, Morg. 



Jamaica : Kingston ; " on citrus imported from India," 15 . iii . 16 (A. H. Ritch 



Chionaspis (Hemichionaspis) minor, Mask. 



Southern Nigeria: Ibadan ; food- plant not stated {I cotton) (Dr. W. A. 

 Lamborn). Gold Coast : Aburi, on Jatropa curcas (W. H. Patterson) ; the female 

 puparia are larger and much more dilated than typical examples ; otherwise they do 

 not materially differ. South Africa : Drakensburg, Cape Province ; on willow 

 trees (D. aVEmmerez). 



Cooley* has described a variety of this species, under the name strachani, from 

 material collected on an unknown plant from Abeokuta, West Africa, and states that 

 it differs from H. minor " in having the exuviae of the female scale rather darker and 

 contrasting more strongly with the secreted portion, and in having the median lobea 

 broader in proportion to their length and more finely and less distinctly crenate." 

 Dr. Lamborn' s examples of the females do not exhibit any morphological characters 

 by means of which one can separate them from typical H. minor ; but the puparia of 

 the females show a somewhat marked departure from Haskell's*)" description in having 

 the secretionary portion much more widely pyriform, dusky white, and relatively 

 thin and smooth. 



Chionaspis dentilobis, Newst. 



Uganda : Entebbe, on an unnamed plant, 6. v. 10 (C. C. Goivdey). 



A large percentage of the females were parasitised, evidently by Chalcidid 

 Hymenoptera . 



Chionaspis (Phenacaspis) lutea, Newst. 



Gold Coast: Aburi, on Funtumia (W. H. Patterson). 



The male puparia associated with the females in this colony are very strongly 

 tricarinate and not at all like those in the type lot described from East Africa. J 

 Possibly the West African examples belong to a species of Diaspis. The $$ are 

 specifically identical with the co-types of G. lutea. 



Fiorinia proboscidaria, Green. 

 Jamaica : Kingston, " on citrus imported from India," 15. iii. 16 (A. H, Ritchie). 

 This species has not hitherto been reported from the West Indies. 



Parlatoria pergandei, Comst. 

 Jamaica: Kingston, "on citrus imported from India, 1913," 15. iii. 16 (A. H. 



Ritchie). 



Parlatoria ziziphus, Lucas. 



Jamaica: Kingston, "on citrus imported from India, 1913," 15. iii. 16 (A. 11. 

 Ritchie).
